Long-Term Pyrene Exposure Of Grass Shrimp, Palaemonetes Pugio, Affects Molting And Reproduction Of Exposed Males And Offspring Of Exposed Females, Eva Oberdörster, Marius Brouwer, Thea Hoexum-Brouwer, Steve Manning, John A. Mclachlan

Faculty Publications

The objective of this study was to investigate the impact of long-term pyrene exposure on molting and reproduction in the model estuarine invertebrate, the grass shrimp (Palaemonetes pugio). Grass shrimp were exposed to measured concentrations of 5.1, 15.0, and 63.4 ppb (mu g/L) pyrene for 6 weeks, during which time we determined molting and survivorship. At the end of the exposure, we immediately sacrificed some of the shrimp for biomarker (CYP1A and vitellin) analyses. The remaining shrimp were used to analyze fecundity and embryo survivorship during an additional 6 weeks after termination of pyrene exposure. Male shrimp at the highest …

Type 1 Plasminogen Activator Inhibitor Binds To Fibrin Via Vitronectin, Thomas J. Podor, Cynthia B. Peterson, Daniel A. Lawrence, Steingrimur Stefansson, Stephen G. Shaughnessy, Denise M. Foulon, Martin Butcher, Jeffrey I. Weitz

Faculty Publications

Type 1 plasminogen activator inhibitor (PAI-1), the primary inhibitor of tissue-type plasminogen activator (t-PA), circulates as a complex with the abundant plasma glycoprotein, vitronectin. This interaction stabilizes the inhibitor in its active conformation. In this report, the effects of vitronectin on the interactions of PAI-1 with fibrin clots were studied. Confocal microscopic imaging of platelet-poor plasma clots reveals that essentially all fibrin-associated PAI-1 colocalizes with fibrin-bound vitronectin. Moreover, formation of platelet-poor plasma clots in the presence of polyclonal antibodies specific for vitronectin attenuated the inhibitory effects of PAI-1 on t-PA-mediated fibrinolysis. Addition of vitronectin during clot formation markedly potentiates PAI-1-mediated …

Nitrogen Cycling In A Forest Stream Determined By A 15n Tracer Addition, Patrick J. Mulholland, Jennifer L. Tank, Diane M. Sanzone, Wilfred M. Wollheim, Bruce J. Peterson, Jackson R. Webster, Judy L. Meyer

Faculty Publications

Nitrogen uptake and cycling was examined using a six‐week tracer addition of 15N‐labeled ammonium in early spring in Walker Branch, a first‐order deciduous forest stream in eastern Tennessee. Prior to the 15N addition, standing stocks of N were determined for the major biomass compartments. During and after the addition, 15N was measured in water and in dominant biomass compartments upstream and at several locations downstream. Residence time of ammonium in stream water (5–6 min) and ammonium uptake lengths (23–27 m) were short and relatively constant during the addition. Uptake rates of NH4 were more variable, ranging from 22 to 37 …

Comparison Of A Dietary Record Using Reported Portion Size Versus Standard Portion Size For Assessing Nutrient Intake, Desiree C. Welten, Ruth A. Carpenter, R. Sue Mcpherson, Suzanne Brodney, Deirdre Douglass, James B. Kampert, Steven N. Blair

Faculty Publications

Objective: Because the percentage of missing portion sizes was large in the Aerobics Center Longitudinal Study (ACLS), careful consideration of the accuracy of standard portion sizes was necessary. The purpose of the present study was to investigate the consequences of using standard portion size instead of reported portion sizes on subjects' nutrient intake.

Methods: In 2307 men and 411 women, nutrient intake calculated from a 3-day dietary record using reported portion sizes was compared with nutrient intake calculated from the same record in which standard portion sizes were substituted for reported portion sizes.

Results: The standard portion sizes provided significantly …

Global System Of Rivers: Its Role In Organizing Continental Land Mass And Defining Land‐To‐Ocean Linkages, Charles J. Vorosmarty, Balazs M. Fekete, M. Meybeck, Richard B. Lammers

Faculty Publications

The spatial organization of the Earth's land mass is analyzed using a simulated topological network (STN‐30p) representing potential flow pathways across the entire nonglacierized surface of the globe at 30‐min (longitude × latitude) spatial resolution. We discuss a semiautomated procedure to develop this topology combining digital elevation models and manual network editing. STN‐30p was verified against several independent sources including map products and drainage basin statistics, although we found substantial inconsistency within the extant literature itself. A broad suite of diagnostics is offered that quantitatively describes individual grid cells, river segments, and complete drainage systems spanning orders 1 through 6 …

Measurement Of Inclusive(D(S)(±)) Photoproduction At Hera Zeus Collaboration, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J. Repond, R. Stanek, R. Yoshida, Margarita C. K. Mattingly, G. Abbiendi, F. Anselmo, P. Antonioli, G. Bari, M. Basile, L. Bellagamba, D. Boscherini, A. Bruni, G. Bruni, G. Cara Romeo, G. Castellini, L. Cifarelli, F. Cindolo, A. Contin, N. Coppola, M. Corradi, S. De Pasquale, P. Giusti, G. Iacobucci, G. Laurenti

Faculty Publications

The first measurement of inclusive D(s)(±) photoproduction at HERA has been performed with the ZEUS detector for photon-proton centre-of-mass energies 130 < W < 280GeV. The measured cross section for 3 < p (is perpendicular to)/(D(s)) < 12GeV and |η(D(s))| < 1.5 is σ(ep → D(s)X) = 3.79 ± 0.59(stat.) -0.46/+0.26 (syst.) ± 0.94(br.)nb, where the last error arises from the uncertainty in the D(s)(±) decay branching ratio. The measurements are compared with inclusive D*(±) photoproduction cross sections in the same kinematic region and with QCD calculations. The D(s)(±) cross sections lie above a fixed-order next-to-leading order calculation and agree better with a tree-level O(αα(s)/3) calculation that was tuned to describe the ZEUS D*(±) cross sections. The ratio of D(s)(±) to D*(±) cross sections is 0.41 ± 0.07 (stat.) -0.05/+0.03 (syst.) ± 0.10(br.). From this ratio, the strangeness-suppression factor in charm photoproduction, within the LUND string fragmentation model, has been calculated to be γ(s) = 0.27 ± 0.05 ± 0.07(br.). The cross-section ratio and γ(s) are in good agreement with those obtained in charm production in e+e- annihilation. (C) 2000 Elsevier Science B.V.

Direct Nitric Oxide Signal Transduction Via Nitrosylation Of Iron-Sulfur Centers In The Soxr Transcription Activator, Huangen Ding, Bruce Demple

Faculty Publications

Nitric oxide (NO) has diverse roles in intercellular communication and (at higher levels) in immune-mediated cell killing. NO reacts with many cellular targets, with cell-killing effects correlated to inactivation of key enzymes through nitrosylation of their iron-sulfur centers. SoxR protein, a redox-sensitive transcription activator dependent on the oxidation state of its binuclear iron-sulfur ([2Fe-2S]) centers, is also activated in Escherichia coli on exposure to macrophage-generated NO. We show here that SoxR activation by NO occurs through direct modification of the [2Fe-2S] centers to form protein-bound dinitrosyl-iron-dithiol adducts, which we have observed both in intact bacterial cells and in purified SoxR …

Low Fasting Plasma Glucose Level As A Predictor Of Cardiovascular Disease And All-Cause Mortality, Ming Wei, Larry W. Gibbons, Tedd L. Mitchell, James B. Kampert, Michael P. Stern, Steven N. Blair

Faculty Publications

Background - Although medical textbooks usually classify fasting plasma glucose <70 or 80 mg/dL (<3.89 or 4.44 mmol/L) as abnormal, the prognosis for patients with low fasting plasma glucose is unclear.

Methods and Results - We conducted prospective cohort studies among 40,069 men and women to investigate the association between fasting plasma glucose levels and cardiovascular disease and all-cause mortality. We documented a U-shaped relation between fasting plasma glucose and mortality. In addition to diabetes and impaired fasting glucose levels, low fasting plasma glucose levels were also associated with high morality. After multivariate adjustment for age, sex, study population, ethnicity, current smoking status, high blood pressure, total cholesterol, body mass index, triglycerides, history of cardiovascular disease and cancer, and a family …

The Q2 Dependence Of Dijet Cross Sections In Γp Interactions At Hera, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J. Repond, R. Stanek, R. Yoshida, Margarita C. K. Mattingly, G. Abbiendi, F. Anselmo, P. Antonioli, G. Bari, M. Basile, L. Bellagamba, D. Boscherini, A. Bruni, G. Bruni, G. Cara Romeo, G. Castellini, L. Cifarelli, F. Cindolo, A. Contin, N. Coppola, M. Corradi, S. De Pasquale, P. Giusti, G. Iacobucci, G. Laurenti

Faculty Publications

The dependence of the photon structure on the photon virtuality, Q2, is studied by measuring the reaction e+p → e+ + jet + jet + X at photon-proton centre-of-mass energies 134 < W < 223 GeV. Events have been selected in the Q2 ranges ≃ 0 GeV2, 0.1-0.55 GeV2, and 1.5-4.5 GeV2, having two jets with transverse energy E(T)/(jet) > 5.5 GeV in the final state. The dijet cross section has been measured as a function of the fractional momentum of the photon participating in the hard process, x(γ)/(OBS). The ratio of the dijet cross section with x(γ)/(OBS) < 0.75 to that with x(γ)/(OBS) > 0.75 decreases as Q2 increases. The data are compared with the predictions of NLO pQCD and leading-order Monte Carlo programs using various parton distribution functions of the photon. The measurements can …

Using The Levels Of Family Involvement Model With Religious Professionals, Dale R. Hawley, Carla M. Dahl

Faculty Publications

Serving as a religious professional is a complex task with a wide variety of demands and responsibilities. This variety contributes to a professional identity that requires the fulfillment of a number of roles. The Levels of Family Involvement (LFI) model (W. J. Doherty, 1995) offers a structure for helping clergy ascertain which roles may be most beneficial to a family in a given set of circumstances, as well as which roles are beyond their training and mission. The LFI is offered as a guideline for helping clergy select modes of intervention and identify areas for personal and professional development. Case …

Fear Of Law: Thoughts On Fear Of Judging And The State Of The Federal Sentencing Guidelines (Sentencing Symposium), Frank O. Bowman Iii

Faculty Publications

To understand Fear of Judging and the debate over the Federal Sentencing Guidelines requires some familiarity with the sentencing reform movement that led to the adoption of the Federal Sentencing Guidelines in 1987, as well as at least a rudimentary grasp of the structure of the Guidelines themselves. For those readers who require an introduction to both subjects, the next section of this Article attempts to provide one. Those already familiar with the Guidelines and their history can skip to Section III, where the discussion of Fear of Judging begins in earnest.

Settlement Patterns And The Origins Of African Jamaican Society: Seville Plantation, St. Ann's Bay, Jamaica, Douglas V. Armstrong, Kenneth G. Kelly

Faculty Publications

Archaeological and historical research at Seville Plantation, Jamaica, are used to explain changes in settlement patterns within the estate's African Jamaican community between 1670 and the late nineteenth century. Sugar plantations, such as Seville, are marked by well-defined spatial order based upon economic and power relations that was imposed upon enslaved communities by planters and managers. Archaeological evidence is used to explore how enslaved Africans modified this imposed order and redefined boundaries in ways that correspond with the development of a distinct African Jamaican society. The rigidly defined linear housing arrangements initially established by the planter, and their relations to …

Nursing Home Residents And The New California Health Care Decisions Law, David M. English, Rebecca C. Morgan

Faculty Publications

This article explores issues involving advance directives made by nursing home residents, both prior to and during their stay in a facility, including the frequency of making directives, the reasons why residents fail to make directives, and the reasons why facilities often fail to honor them. Specifically, this article examines these issues in light of the 1999 California Health Care Decisions Law, effective July 1, 2000, and focuses on how this new statute can be used to empower nursing home residents, and adults more generally, to take control of decisions regarding their own health care.

The Case Against Private Disparate Impact Suits, Thom Lambert

Faculty Publications

This article argues that the Third Circuit, and the courts that have implicitly approved private disparate impact suits, have erred in construing Title VI to permit private plaintiffs to sue federally funded entities for discrimination based on disparate impact alone. From a policy standpoint, permitting private disparate impact suits is a bad idea, for the threat of such suits will lead to deterrence of actions and decisions that have incidental disparate effects but are, on the whole, good.

Who Should Control The Decision To Call A Witness: Respecting A Criminal Defendant's Tactical Choices, Rodney J. Uphoff

Faculty Publications

A law student approached me not long ago to discuss a problem he had encountered while helping to prepare a criminal case for retrial. The defendant's first trial ended with a hung jury. The defendant, Steven Brown, now faced a second trial on the same misdemeanor charge of assaulting a police officer. Although the defendant still wanted to go to trial, Brown told defense counsel that he did not want his elderly father to have to testify again. From defense counsel's standpoint, the father's testimony was critical because he was the only witness corroborating the defendant's version of the event. …

Alcohol Intake And Mortality: Findings From The National Health Interview Surveys (1988 And 1990), Youlian Liao, Daniel L. Mcgee, Guichan Cao, Richard S. Cooper

This article summarizes parts of Lee’s forthcoming article “A Populist Political Perspective of the Business Tax Entities Universe: Hey the Stars Might Lie But the Numbers Never Do,” 78 Texas L. Rev. 885 (2000). Conventional wisdom, says Lee, holds that the LLC, due to its limited liability and hassle-free single level of taxation, will supplant C and S corporations as the choice of entity for new businesses. In fact, in most jurisdictions corporate formations outnumber LLC formations 2:1 or more, and IRS Statistics of Income (SOI) projects that the S corporation will be the fastest growing tax entity for 2000 …

Faculty Publications

The forward-jet cross section in deep inelastic e + p scattering has been measured using the ZEUS detector at HERA with an integrated luminosity of 6.36 pb -1 . The jet cross section is presented as a function of jet transverse energy squared, E(T,jet)/ 2 , and Q 2 in the kinematic ranges 10 -2 < E(T,jet)/ 2 /Q 2 < 10 2 and 2.5 · 10 -4 < x < 8.0 · 10 -2 . Since the perturbative QCD predictions for this cross section are sensitive to the treatment of the log(E(T,jet)/ 2 /Q2) terms, this measurement provides an important test. The measured cross section is compared to the predictions of a next-to-leading order pQCD calculation as well as to various leading-order Monte Carlo models. Whereas the predictions of all models agree with the measured cross section in the region of small E(T,jet/ 2 /Q 2 only one model, which includes a resolved photon component, describes the data over the whole kinematic range.

Correlates Of Physical Activity In Male And Female Youth, Timothy Bungum, Marsha Dowda, Anne T. Weston, Stewart G. Trost, Russell R. Pate

Faculty Publications

This study examined associations between psychosocial factors and physical activity in a group of youth (n=520). Students completed the Previous Day Physical Activity Recall and a survey of potential determinants of physical activity. Regression analyses of intentions to be physically active revealed that enjoyment and self-efficacy predicted intentions for both males and females. Attitudes predicted moderate to vigorous activity (MVPA), and enjoyment and self-efficacy predicted vigorous activity (VPA) for males. Self-efficacy predicted both MVPA and VPA for females. The findings suggest that intervention programs targeted at youth should include developmentally appropriate activities that are fun and promote physical …

Responses Of Phytoplankton And Pfiesteria-Like Dinoflagellate Zoospores To Nutrient Enrichment In The Neuse River Estuary, North Carolina, Usa, James L. Pinckney, Hans W. Paerl, Elin Haugen, Patricia A. Tester

Faculty Publications

The recently described toxic dinoflagellate Pfiestena piscicida and morphologically similar Pfiesteria-like dinoflagellates have become a major water quality issue with possible fish mortality and reported human health implications. The linkages between accelerated nutrient loading, eutrophication, and the proliferation of this group of dinoflagellates, however, are not well established for natural Systems. Phytoplankton pnmary production may provide a key link between nutrient inputs and potential outbreaks of Pfiesteria-like biflagellated zoospores in the Neuse River Estuary, North Carolina. The impacts of nutrient (NO₃^- -nitrogen and PO₄^3- -phosphorus) supply rates, sediment-water column exchange, water column mixing, and phytoplankton prey …
